Storing hydrogen in the liquid form requires a 64% higher amount of energy than that needed for high-pressure hydrogen gas compression, where hydrogen does not liquefy until −253 C [18], and cooling that far is an energy-intensive process [19].

The production, storage and transportation of ammonia are industrially standardized. However, the ammonia synthesis process on the exporter side is even more energy-intensive than hydrogen liquefaction. The ammonia cracking process on the importer side consumes additional energy equivalent to ~20% LHV of hydrogen.

The hydrogen content of ammonia is 17.6 wt%, which is known as indirect hydrogen energy storage. The energy density of ammonia is 4.32 kWh/L, which is the same as methanol (CH 3 OH) [ 34 ]. The liquefying process of hydrogen is too difficult when compared to ammonia, which can be liquefied at −33.4 °C and at atmospheric pressure.
